Should they? Yes.

"Does the “deep ecology” philosophy bear any guilt for those deaths since it advocates reducing the earth’s population to a fraction of what it is now, even if by “natural” means like malaria?"

Guilt didn't drive them to insanity, so it really won't affect them either way.

I have no objection to allowing the Earth's population to be reduced. Some of us want to get out of this looney-bin anyway.

I'd like to retire to one of the cloud-cities of Venus.

I know what you mean. When I was younger life was a waltz, now it's a barroom brawl with a knee to the groin and a thumb in the eye everyday. And the ref sticks a foot out to trip me.
If the cloud cities of Venus were any good the taxes would be out of my league. Cheers
